RESUMO
A 58-year-old woman was diagnosed with a left-sided lone internal mammary swollen lymph node on a routine follow-up computer tomography, 42 months after a left mastectomy in the context of a ductal carcinoma grade III. The suspected metastasis was successfully removed in toto using a 3-port-da Vinci robotic procedure and the patient was discharged home without any complication on the third postoperative day. Robotically assisted oncological lymph node removal is safe, easily performed and economically affordable.

AIMS: Left ventricular (LV) lead implantation through the coronary sinus (CS) can be limited and sometimes not possible-alternative approaches are needed. Minimally invasive, robotically guided LV lead implantation has major advantages, but there are little published data about the short- and long-term follow-ups, in terms of feasibility, safety, electrical performance, and impact on clinical outcome. METHODS AND RESULTS: A total of 21 heart failure patients underwent robotically guided LV lead implantation using the Da Vinci Robotic System. Indications were failed implant with conventional approach through the CS (n = 16) and non-response to conventional cardiac resynchronization therapy (n = 5). During the procedure, the entire LV free wall was exposed through 3 transthoracic ports (10 mm diameter each) allowing ample choice of stimulation site and the ability to implant 2 LV leads via a Y connector. Patients were prospectively followed up for 1 year. The two LV leads were successfully implanted in all patients. No peri-procedural complications were observed. After a mean stay in the intensive care unit of 1.2 ± 4 days, the 21 patients were hospitalized in the EP department for 6.7 ± 2.9 days. Acute LV thresholds were excellent (1.0 V ± 0.6/0.4 ms) and stayed stable at 1-year follow-up (1.5 V ± 0.6/0.4 ms, P = 0.21). Four patients demonstrated an increased threshold (>2 V/0.4 ms). There was no phrenic nerve stimulation. After 12 months, in the failed implant group, 69% of the patients were echocardiographic and clinical responders. CONCLUSION: The robotic approach was feasible, safe, and minimally invasive. Accordingly, robotically guided LV lead implantation seems to offer a new alternative when conventional approaches are not suitable.

Background Chronic Kidney disease is a major health problem in the world. Native arteriovenous Fistula (AVF) is well established as the best vascular access for haemodialysis. Little is known about the outcome of AVF in sub-Saharan Africa. We aim to analyze the outcome of patients undergoing AVF creation during the pilot program established at the Douala general hospital (DGH). Method This was hospital-based, longitudinal study with a retrospective phase (April 2010-January 2014) and a prospective phase (January 2014-April 2014). All consecutive patients operated for AVF creation were included in this study. Socio-demographics data, functionality, and complications were analyzed. Results Eighty-one patients including 52 men were enrolled in this study (49 prospectively and 32 retrospectively). The mean age was 52, 3 years (range 18-81 years). Hypertension (66, 7%), diabetes (17, 3%), and HIV (8, 6%) were the most observed co-morbidities. About 96.3% of AVF were native and 3.7% were prosthetic graft. Radiocephalic AVF was performed at a rate of 77.8%. The primary function rate was 97.7% and the mean follow-up period 43.4 weeks. The overall rate of complications was 44.4% of whom 30.5% were early, 30.5% secondary, and 39% lasted. The treatment of these complications was conservative in 48.7% of cases. Conclusions The results of the pilot program of AVF creation at the DGH are encouraging. However, the sustainability of this project requires human capacity building.

OBJECTIVES: The robotic totally endoscopic coronary artery bypass graft (TECAB) surgery reduces patients' recovery time. The present trial investigated the feasibility and safety of an initial enhanced recovery after surgery (ERAS) path for patients undergoing robotic beating-heart TECAB and compared it with both conventional surgery and traditional perioperative care. It was hypothesized that the preliminary ERAS pathway associated with a beating-heart TECAB procedure could have a synergistic effect on postoperative patient care. DESIGN: Observational retrospective study. SETTING: University hospital. PARTICIPANTS: Patients scheduled for coronary artery bypass graft and undergoing robotic beating-heart TECAB (n = 38) were compared with those undergoing standard surgery and perioperative care (n = 33). The outcomes were the possibility of tracheal extubation at the end of the surgery and the incidence of postoperative complications. MEASUREMENTS AND MAIN RESULTS: The main comorbidities were similar between the 2 groups. Extubation on the operating table in the TECAB group was possible in all cases without requiring prompt endotracheal tube reinsertion. The proportion of patients transfused was significantly lower in the TECAB group (p = 0.009). In addition, the duration of intensive care unit and hospital stay were reduced significantly by 24 hours and by 4 days, respectively, in the TECAB group compared with the standard group (p< 0.05). CONCLUSIONS: The present results suggested that a program coupling a beating-heart TECAB with a preliminary ERAS path for patients requiring a single coronary revascularization is feasible and safe. This approach could reduce postoperative mechanical ventilation time, transfusion rate, and both intensive care unit and hospital stay.

BACKGROUND: Minimally invasive procedures have demonstrated their effectiveness in reducing the recovery times while ensuring optimal results and minimizing complications. Regarding the coronary artery surgical revascularization field, the evolution of techniques and technology is permitting new surgical strategies that are increasingly precise and suitable for each patient. We present an initial single center experience with a case series of patients successfully treated with combined robotic harvesting of the left internal mammary artery (LIMA) and minimally invasive direct coronary artery bypass graft (MIDCAB) for the anastomosis. METHODS: We retrospectively reviewed the records of patients who underwent minimally invasive coronary artery revascularization with the use of two combined techniques at our Institution between January 2021 and October 2022. RESULTS: A total of 17 patients underwent coronary artery bypass grafting with the described approach. The median cardiopulmonary bypass (CPB) and cross-clamp times were 83 min (76-115) and 38 min (32-58), respectively. The median intensive care unit (ICU) and hospital stay were 2 days (1-4) and 8 days (6-11), respectively. The procedure's success was achieved in 100% of patients. The 30-day mortality was 0%. CONCLUSIONS: Considering all the limitations related to the small sample, the presented results of a hybrid approach for minimally invasive coronary artery bypass grafting (CABG) appears to be encouraging and acceptable. The main advantage of this approach is related to the reduction of postoperative pain and pulmonary complications.

RESUMO
(1) Background: Although transcatheter technology is rapidly growing and represents a promising strategy, the surgical approach remains the best way to repair a degenerative mitral valve regurgitation. In this context, robotic surgery is technologically the most advanced method of minimally invasive mitral valve repair. The aim of this study is to present the preliminary results of the initial single-center experience with a new robotic mitral valve repair program. (2) Methods: We retrospectively reviewed the records of patients who underwent robotic mitral valve repair at our Institution between January and September 2021. (3) Results: A total of 29 patients underwent mitral valve repair with annuloplasty and chordal implantation to treat degenerative mitral regurgitation. The procedure's success was achieved in 97% of patients. The 30-day cardiac-related mortality was 0%. The median CPB and cross-clamp times were 189 and 111 min, respectively, with a progressive reduction from the beginning of the robotic program. (4) Conclusions: Considering all the limitations related to the small sample, the presented results of robotic mitral valve repair appear to be encouraging and acceptable. A careful patient selection, a dedicated team, and a robust experience in surgical mitral valve repair are the fundamentals to start a new robotic mitral surgery program.
RESUMO
BACKGROUND: European surgeons were the first worldwide to use robotic techniques in cardiac surgery and major steps in procedure development were taken in Europe. After a hype in the early 2000s case numbers decreased but due to technological improvements renewed interest can be noted. We assessed the current activities and outcomes in robotically assisted cardiac surgery on the European continent. METHODS: Data were collected in an international anonymized registry of 26 European centers with a robotic cardiac surgery program. RESULTS: During a 4-year period (2016-2019), 2,563 procedures were carried out [30.0% female, 58.5 (15.4) years old, EuroSCORE II 1.56 (1.74)], including robotically assisted coronary bypass grafting (n = 1266, 49.4%), robotic mitral or tricuspid valve surgery (n = 945, 36.9%), isolated atrial septal defect closure (n = 225, 8.8%), left atrial myxoma resection (n = 54, 2.1%), and other procedures (n = 73, 2.8%). The number of procedures doubled during the study period (from n = 435 in 2016 to n = 923 in 2019). The mean cardiopulmonary bypass time in pump assisted cases was 148.6 (63.5) min and the myocardial ischemic time was 88.7 (46.1) min. Conversion to larger thoracic incisions was required in 56 cases (2.2%). Perioperative rates of revision for bleeding, stroke, and mortality were 56 (2.2%), 6 (0.2 %), and 27 (1.1%), respectively. Median postoperative hospital length of stay was 6.6 (6.6) days. CONCLUSION: Robotic cardiac surgery case numbers in Europe are growing fast, including a large spectrum of procedures. Conversion rates are low and clinical outcomes are favorable, indicating safe conduct of these high-tech minimally invasive procedures.
RESUMO
A 56-year old man presented with increasing angina pectoris. Coronary angiogram showed a triple-vessel disease, with significant lesions on the main stem, on an obtuse marginal branch of the circumflex coronary artery (Cx), on the right coronary artery (RCA), and a proximal occlusion of the left anterior descending artery (LAD). A hybrid procedure was decided, with a beating heart totally endoscopic double vessel coronary artery bypass grafting (Double BHTECAB) on the LAD and the Cx, with the use of a four-arm robotic device, and a stent placement into the RCA in a second step. Both procedures went uneventfully, and the patient is fully asymptomatic 15 months after the procedure.

BACKGROUND: Cardiac surgery is a growing activity in Sub-Saharan Africa, however, data related to long-term mortality are scarce. We aimed to analyze outcome data of cardiac interventions in two hospitals in Cameroon over 10 years' period. METHODS: we conducted a retrospective analytical and descriptive study at the Douala General Hospital and Yaoundé General Hospital. All patients operated between January 2007 and December 2017, or their families were contacted by phone between January and April 2018 for a free of charges medical examination. RESULTS: Of a total of 98 patients operated during the study period, 8 (8.2%) were lost to follow-up. Finally, 90 patients [49 (54.4%) women and 41 (45.6%)] men were included. The mean age was 49±22 years (range, 13-89 years). The surgical indications were valvular heart diseases in 37 (41.1%) cases, congenital heart diseases in 11 (12.2%) cases, chronic constrictive pericarditis in 4 (4.4%) cases, and intra cardiac tumor in 1 (1.1%) case. Valve replacement was the most common type of surgery carried out in 37 (41.1%) cases-mostly with mechanical prosthesis. Pacemaker-mostly dual-chambers were implanted in 36 (40.0%) patients. The median follow-up was 26 months. The overall late mortality was 5.7%, and the overall survival rates at 5 and 10 years were 95.5% and 94.4% respectively. The overall survival rates at 5 and 10 years for mechanical valve prosthesis were 93.3% and 90% respectively. The survival at 10 years was 100% for patients with bioprosthesis. The survival rates at 10 years were 94.1% and 100% respectively for dual and single chamber pacemaker. CONCLUSIONS: Long-term outcome of cardiac surgery in hospitals in Cameroon are acceptable with low mortality rate. However, outcome metrics beyond mortality should be implemented for a prospective data collection.
RESUMO
Coronary artery bypass grafting (CABG) remains the most common cardiac surgery performed today worldwide. The history of this procedure can be traced back for more than 100 years, and its development has been touched by several pioneers in the field of cardiac surgery, who have contributed with both their successes and failures. With ever increasing follow up and number of patients treated, thinking regarding optimal CABG technique evolves continually. This article reviews the history of CABG from its early experimental work to recent technological advances.
RESUMO
Cardiac surgery with extracorporeal circulation (ECC) is usually associated with the loss of a significant amount of blood. Adequate prophylaxis against blood loss and good perioperative hemostasis are known as processes limiting postoperative bleeding. Until now, the need for platelets in patients operated with extracorporeal circulation in our Department has been compensated for by total blood transfusion or platelet concentrates collected from several donors. We here report our first experience with platelet concentrate collection by apheresis at the General Hospital in Douala.

BACKGROUND: Cardiac resynchronization therapy (CRT) by pacing the left and right ventricles is an emerging option for treatment of severe heart failure with ventricular conduction disturbances. Stimulation through a coronary vein is currently the technique of choice to achieve left ventricular (LV) pacing. Unfortunately, this approach carries significant limitations and drawbacks. Therefore we explored robotic-enhanced thoracoscopic implantation of an epicardial lead as an alternative technique to stimulate the LV in cardiac resynchronization therapy. METHODS: A total of 15 patients were included in this study. Right (atrial and ventricular) leads were implanted classically through the left subclavian vein. Robotic-enhanced thoracoscopy was then performed to implant the LV epicardial lead. RESULTS: Of the 15 patients, 13 underwent successful endoscopic robotic cardiac resynchronization therapy. Two patients underwent conversion to a small thoracotomy. No perioperative complication occurred in the patients who did not undergo conversion. Acute and chronic LV lead thresholds were satisfactory in all patients, improving over time. All were subjectively and objectively improved at 4 months. As compared with conventional methods, the procedural cost was not significantly affected. CONCLUSIONS: Based on this feasibility study, we believe that robotic LV epicardial lead implantation is a valuable option to achieve biventricular resynchronization therapy. It allows for more reproducible acute thresholds for LV pacing and sensing than does the percutaneous approach; enables fine tuning of the LV lead position, thus potentially providing optimal hemodynamic benefit; and avoids the pitfalls and limitations of the endovenous approach. Therefore it deserves further prospective studies to assess its place in the therapeutic armamentarium against heart failure.

BACKGROUND: We report a clinical study to demonstrate the feasibility and safety of a new aortic crossclamping concept for use in port-access cardiac surgery. The limited access to the aorta in minimally invasive cardiac surgery mandates specific clamping modalities, which entail specific limitations, drawbacks, and costs. Therefore a new autoguided, extravascular, and atraumatic clamping system (PortaClamp) was developed to facilitate port-access surgery while potentially avoiding the complications and costs inherent to endoluminal clamping or "blind" crossclamping. METHODS: Twenty patients underwent various cardiac operations under cardiopulmonary bypass and aortic crossclamping with the PortaClamp between February and September 2003. The method of aortic clamping is described and the operative course and clinical outcome of the patients are reported as surrogates of feasibility and safety. RESULTS: The average time to position the clamp was 196 +/- 75 seconds. Crossclamping through a 10-mm port or incision was achieved successfully, enabling cardiac arrest throughout the procedure in every patient. No patient presented with cardiovascular accident or transient ischemic attack, aortic dissection, or hematoma. Intensive care unit times were 12 +/- 3 hours; length of stay was 7.2 +/- 1.1 days. CONCLUSION: From this early experience we conclude that the PortaClamp system is safe and can effectively be used to crossclamp the aorta inexpensively to facilitate port-access cardiac surgery. Further comparative studies with the existing systems are warranted to confirm that the atraumatic design provides further benefit.

PURPOSE: For optimal biventricular pacing, the left ventricular (LV) lead has been found to be best placed in the area where optimal concordance is achieved between the LV pacing site and the site of the most delayed LV wall. For anatomical or technical reasons, the placement of the LV lead via the coronary sinus at the intended target area of the LV is often not possible. An option for avoiding these drawbacks is the surgical implantation of the LV lead under direct vision. This report describes 3 epicardial lead implantation techniques that are less invasive. METHODS: In 80 patients with advanced heart failure and left bundle branch block, epicardial LV leads for biventricular pacing were implanted with 3 different methods: (1) left lateral mini-thoracotomy; (2) a video-assisted thoracoscopy approach using lead implantation tools; and (3) a robotically enhanced telemanipulation system. Video films are provided for all 3 techniques in The Heart Surgery Forum online. RESULTS: Independent of the surgical techniques, the intended lead location on the LV was achieved in all patients. Acute and 3-month LV lead thresholds were satisfactory in 79 patients (99%). Two lead displacements were observed. One thoracotomy was carried out after thoracoscopic lead placement because the patient developed an early exit block. Five patients who underwent an operation with the robot needed a conversion to thoracotomy because of technical failure of the robot (2 patients) or massive pleural adhesions (3 patients). There were no severe adverse events related to any technique. Three patients died in the hospital from the progression of end-stage heart failure. CONCLUSION: Epicardial lead implantation for biventricular pacing is feasible with all 3 surgical techniques. Each method allows optimal lead implantation under direct vision and therefore reduces the incidence of nonresponders resulting from suboptimal lead placement.

BACKGROUND: Pulmonary vein isolation (PVI) has been shown to be effective treatment of patients with symptomatic paroxysmal atrial fibrillation (PAF). The percutaneous approach is currently the technique of choice. Unfortunately, this procedure has limitations and complications that lead to fluctuating success rates. We explored an alternative technique of robotic-enhanced, closed-chest PVI with an endoscopic microwave-based catheter. METHODS: Seven symptomatic PAF patients were included in the study. The pulmonary veins were isolated through right (only) robotic-enhanced thoracoscopy on the beating heart. RESULTS: Six patients underwent successful endoscopic PVI. In 1 patient the operation was converted into small right thoracotomy. Operative assessment of the ablation line showed a successful electric block in every patient. Three months after the procedure, the first 5 patients were in permanent sinus rhythm. The 2 other patients had AF but had less frequent and less symptomatic episodes compared with the preoperative situation. CONCLUSIONS: On the basis of this preliminary experience, we believe that in the near future endoscopic right-chest robotic-enhanced PVI on the beating heart may become a valid option in the treatment of symptomatic PAF patients. This procedure allows for more-reproducible ablation lines and may avoid many of the pitfalls and drawbacks of the percutaneous approach. Therefore this technique deserves larger prospective evaluation in the treatment of AF.

To assess the advantages of a ministernotomy over a standard sternotomy for aortic valve replacement, 191 patients were classified as low-, medium-, and high-risk by EuroSCORE. A ministernotomy was carried out in 100 patients, and a standard sternotomy was used in 91. Among low-risk patients, those who had a ministernotomy showed a marginal increase in atrial fibrillation. Of the medium-risk patients, those who had a sternotomy had significantly more atrial fibrillation and slightly more general infections. In the high-risk subgroup, significantly more atrial fibrillation was observed in the sternotomy group, and more neurologic events were observed in the ministernotomy group; the difference became nonsignificant when only severe events were considered. There was a significant benefit in terms of rhythm disturbances in medium- and high-risk patients who underwent a ministernotomy compared to those who had a full sternotomy. Mortality, duration of intensive care, and hospital stay were not influenced by the operative method.
